Abstract
A method includes introducing at least one of a whole product or a milled product (e.g., corn) to an airflow (e.g., using a gravity hopper), directing the airflow into one or more accelerators, separating a first fraction of the at least one of the whole product or the milled product from a second fraction of the at least one of the whole product or the milled product in the one or more accelerators. For example, corn germ, starch, and bran components can be separated from one another.
Claims20
A method comprising:
- introducing a milled product to an airflow, the milled product having a moisture content ranging between thirteen percent (13%) and eighteen percent (18%);
- directing the airflow including the milled product into an accelerator, the accelerator comprising an ingress diameter and an egress diameter, wherein the ingress diameter is larger than the egress diameter;
- and
- degerming a first fraction of the milled product from a second fraction of the milled product in the accelerator.
1 more element
A system comprising:
- an air mover for generating an airflow having a speed between three hundred and five miles per hour (305 mph) and four hundred miles per hour (400 mph) to maintain the airflow at a temperature above one hundred and twenty degrees Fahrenheit (120° F.), the airflow comprising a milled product, wherein the air mover is operated between at least three thousand pounds per square inch (3,000 psi) and five thousand pounds per square inch (5,000 psi);
- and
- an accelerator for receiving the airflow including the milled product and degerming a first fraction of the milled product from a second fraction of the milled product, the milled product having a moisture content ranging between thirteen percent (13%) and eighteen percent (18%), the accelerator comprising an ingress diameter and an egress diameter, wherein the ingress diameter is larger than the egress diameter.
A method comprising:
- dehydrating a milled product such that the milled product has a moisture content ranging between thirteen percent (13%) and eighteen percent (18%);
- introducing the milled product to an airflow generated by an air mover, wherein the air mover is operated between at least three thousand five hundred pounds per square inch (3,500 psi) and four thousand pounds per square inch (4,000 psi);
- directing the airflow including the milled product into an accelerator, the accelerator comprising an ingress diameter and an egress diameter, wherein the ingress diameter is larger than the egress diameter;
- maintaining the airflow at a temperature above one hundred and twenty degrees Fahrenheit (120° F.);
- and
- degerming a first fraction of the milled product from a second fraction of the milled product in the accelerator.
